Abstract
A vehicle display system includes a display having a display screen which displays an image and provides a touch screen user interface. A controller of the display includes a touch detector which detects a number of fingers touched to a predetermined portion of the display screen, as well as a direction and distance of movement of the number of fingers away from the predetermined portion of the display screen. A navigation mode determiner of the controller determines a navigation mode based on the detected number of fingers. A navigation feature determiner of the controller determines a navigation direction and navigation rate based on the detected direction and distance the number of fingers is moved. An image navigation controller of the controller controls the display to navigate the image displayed on the display screen according to the determined navigation mode, navigation direction, and navigation rate.
